I kinda doubt it. Once summer is over, attendance will drop. Events like this are expensive. I can't imagine they'll want the expense of nightly fireworks for the fewer people who will be there come September.
SoA will also start its annual Osborne makeover then as well. I could see the show at the Premiere Theater continuing, but that will probably be it.
Particularly with AI:E closing in January, I hope that they leave the show in the Premier Theater on a more permanent basis. And I hold out hope (although slim hope) that the popularity of fireworks at DHS will cause Disney to bring back a nightly fireworks show there, even if only on a seasonal basis (summer, Xmas/NewYears, spring break).
Of course, my real dream is that TDO 1) sees that nightly fireworks at DHS are hugely popular, and 2) sees that a "special" fireworks show is a great idea, and then decides to have two or three different fireworks shows that rotate. Frozen fireworks twice a week, Star Wars fireworks twice a week, etc. But that's really dreaming.
